Hello all, i wrote time ago this item in the firebird-support list, but
vlad suggest to write it in the devel list.
The question is that doing some test, i use one udf function in one dll
that raises an exception that the function did not catch.
When that exception raised, the firebird engine

why instead crush the engine when an exception is raised, the engine would

write in the log the error?
How??? How the engine catch an alien exception? Could you show the method
working in
MSVC and GCC?

I don,t know how and if is possible, There must be a point in firebird
where a call to an udf in a dll is executed, and i don't know if is
possible to catch an exception that is raised in
CORE-3671 describes a JVM access violation which occurs when a Java
application using Firebird embedded exits when a connection hasn't been
closed.
The solution / workaround is of course to close() the connection from
Java. I am however uncertain if this could be indicative of a problem
in
The engine does what is possible and tries to catch the 'alien exception'.
You must do your part and write a correct UDF, testing them before in
non-production environment.

I know it, and is not me, is firebird. I try To test everything, but nothing is
perfect. One simple

But it will make OS to close your application harshly. Exactly as it is done
with Firebird.

My example was not a good example, i knew it Just after pressing send button.

Because every programmer know that exceptions can hardly pass boundaries of
DLL. Now it
is time for you to learn it too.

Thank you very much for the lesson, but you say can hardly not can't.
Sorry for the post and for waste your valuable time with me.

Right. But I'm not going to describe how many stars must have right
positions to allow
that.

Thank you again for the lesson, i did never link the positions of thr stars
with programming, but i'll take it into account the next time.

First off to say that I fully agree that a UDF must not let
exceptions escape. I have no issue with that.
Claudio says in the v2.1.4 release notes: Since UDFs have no
formal mechanism to signal errors, the returned value would
have to be used as an indicator.
I was wondering if anyone had had
